Subject: [PATCH v5 0/3] mfd: Intel SoC Power Management IC

Devices based on Intel SoC products such as Baytrail have a Power
Management IC. In the PMIC there are subsystems for voltage regulation,
A/D conversion, GPIO and PWMs. The PMIC in Baytrail-T platform is called
Crystal Cove.

This series contains common code for these PMICs, and device specific
support for Crystal Cove.

v2:
- Use regmap instead of creating our own I2C read/write callbacks.
- Add one missing EXPORT_SYMBOL.
- Remove some duplicate code and put them into pmic_regmap_load_from_hw.
v3:
- Use regmap-irq and remove lots of duplicate code.
- Remove 2 unused APIs.
- Some other cleanup.
v4:
- Remove all exported APIs which are wrappers of regmap API, export
  the regmap in data structure instead.
- Combine intel_soc_pmic_core.c and intel_soc_pmic_i2c.c
- Clean up include files.
- Remove useless members of struct intel_soc_pmic_config.
- Fix various coding style issues.
v5:
- Add comment to describe what is done in _find_gpio_irq().
- Remove i2c id. Only keep ACPI id and match it in _probe().
- Further fix of coding style issues.
- Add the GPIO patch, to merge it along with the MFD changes.

Zhu, Lejun (3):
  mfd: intel_soc_pmic: Core driver
  mfd: intel_soc_pmic: Crystal Cove support
  gpio: Add support for Intel Crystal Cove PMIC
